Chara may have a broken jaw. Would (no pun intended) be a big loss and (pun intended) a tall order for the Bruins to overcome.
I would think that the risk of additional major damage would be too high as even though as tall as Chara is he could still get a shoulder, elbow, stick, or another puck to the same spot.Can he still play with a full mask? Or, is that too risky? (I mean his arms and legs still work.)
Even with a full cage the impact could be enough to aggravate the existing injury.
